Application filed June 4,

To all whom it may' (zo/noem.' Be it known that WoLreANo E. bouw/AnzA 4MANN and Aoonru Roennn, citizens of thc United States, residing atand whose ostoice ecldrees ere, respectively, 51 elle claire Avenue, Longmeadow, und-4l Ventura Street, Springfield, in the county of Hemp den and Stute ot Massachusetts, have in* vented certain nervi and useul'lmproveinents in TmerDistributors; and we do hereby dec-lere the ollownlr to be a full; clear, and exact description vo the invention, suoliA as will enable othersl'skilled in the art to which it appertains, to make'end use the sume. i

The 4present invention .relates totimerdistributors for electrioigniti'on' systems for" intern'ul combustion'. engines.

respect to the venting rotation of relative to the latter.

Within the chamber of the housing 1 is provided an oil well 36 which contains n quantity 'of oil or other lubricant adapted, t uring the operation of the governor mechanism, to be splashed about within the chamber of the casin l, so as to constantly and automatically lu ricate the various parts of the governor mechanism. The shaft (i, however1 is provided with an oil deflectin'g ring or collar 37 at the upper portion of the chamber, adapted, during the 'rotation of the shaft, to oentrifugelly cast oli or deflect an oil that may have Worked its way u wardly alongr the shaft or splashed upward 3 Within the' overnor housing so es to* 'ard ie access into the interior of the cup governor housing, thus pre the former upon and through tho o ening38 'lower wall 12 oithe cup. l

Upon'the outside, of the housing' 1 may be suitably attached a neme plate`39, 'inl the vfornijofa band, secured to 'the housing by means of 'escutcheon pins 40, if desired? [At the upper ond'of'the governor housing 1 are provided, on the opposite side-s thereof, bosses 41 throuvfh wh'ch extendiollow rivets or eyelets 4.2, etween the outer {langesfof which and the bosses 41 are secured pivot straps vor 'hinge members 43. The lower 'ends ofthe latter are curved -to provide `bearings or lseats ivotally mounted spring clips 45, lhooked end portions 46 of which the upper l are adapted to clasp with the distributor cap 3 upon the shoulders 47 thereof, the

spring clips thus acting to retain the housing 1, cup 2 and the distributor cap'3 inassem- 43 to the sides of the housing land to also permit the entry of air for air circulation Ywithin the interior of the device and the venting offoul gases therefrom, the c up 2 bein'g provided with suitable apertures 48 located in register with the passa es of the rivets 42, as is clearly shown in ig. 1 of the drawing.

lt will be apparent that the cu is constructed so as to rest or iit within t e upper end portion of the supporting member or housing 1, and is readily detachable therefrom so as to permit read inspection of the interruptor mechanism.v y having a complete interrupter mechanism within Ya, detachable housin orcu so that the whole device may be etache and yet be capable of bein inspectedand tested is a. new feature mld is part of our invention. The cup is preferably formed by drawing it from a. ieee of sheet metal into the form shown in ig. 2 and of s diameter to slidably and snugly fit in the upper open end of the hous fThe-cup will accordingly have its provided in the -of the cup w. `.block '14"operate.

This is accomplished by' means of suitable tools, suc las a punch and die, the former being'. applied-internall ofthe cup tov force a portion'of the meta thereof outwardly `against, a die, of suitable-shape, applied cxteriorl'y of thc cup at the desired oint oppositethe point of application of the tool. The displacement of the metal by the 'punch is S0 shown by therecess 53.-' In placing the cup in the housing 1, the seats 52 willsit squarely Aon the shelf'l thus'li'rniting the inner movement ofthe cup. It will be noted that these seats 'areloceted'atA the outermost points of Si the cupkso that any possible slight varia-tion in lpositlon mtheir coactio'n'wlth the rshelf1 w1 not be a preciable at the central-region ere-'the' interrupter cani 9 and ity of theicup-tilting'rvithgrespect 'to the axis of the shaft 6 is precluded; This "is -also aided by the heightofthe'peripheralfiange of .the c'up'which byireasonof its close fit within the openrend of the-housing l -'ur-thel *'96 prevents tilting-'action of the cup.

It will he observed that the peripheralniiange of the cup projects upwardly beyond theend of the housing 1 and thus 'fits into and conci-.s with the lower -rini of the distributor cap 3, so as to center the cap, and the terminals car ried by it, in correct relation with the rotor insert. The cap also has a high tension V lower end of which is located a; contact brush 460 in rubhing contact with the insert' 58.'
